8.2 Maintenance operations

8.2.1 Opening the condensation drain hole

) Note!

ƒ Depending on the mounting position, the condensation drain holes are

always at the bottom of the motor!

ƒ For condensate drainage

– the motor must be deenergised;

– the plugs (screws) must be removed.

( Stop!

To restore the enclosure, re−insert the plugs (screws) after condensate

drainage. If the condensation drain holes are not sealed again, the IP enclosure

of the motor will be reduced. For horinzontal motor shafts to IP23 and for

vertical motor shafts to IP20.

The required maintenance intervals strongly depend on the corresponding ambient and

operating conditions. Initially, the condensation drain holes should be opened more

frequently (at least once a week) to obtain experimental values for the condensate

quantity arising.
